A part for the formation of existing example embodiment, will identify and call for Votes first.
According to the existing standard (such as RFC and 3GPP TS) for diameter credit control, represent a service or one group to usual
Start when payload coupling RG should be detected at the credit of grading group RG of service in GW.Because GW has to wait for being derived from
The response of OCS, thus this leads to " excessively using " risk when service should be prevented from.This also results in " delay of redirection "
And user must retry access service again to redirect.
As subscriber, due to insufficient credit or other limit when should be prevented from use that certain service or subscriber should be reset
To boost sales or supplement door with money when, in the case that home subscriber roams just in other networks, a lot of operators lose income.
But the payload of initiation quota control is passed through service network is finally abandoned by ownership GW due to diameter credit control.Ownership
Operator is necessary for the payload passing through and pays roaming partner, although home-operator do not obtain with regard to its
Any income.
Scheme presented herein is to reduce the type " income leakage loss " and at its best by loss conversion
It is to increase, in the case of executing redirection by using diameter credit control instruction (directive) of trying to be the first, the probability sold.Reset
Should shift to an earlier date to instruction, the request of prevention service and allocation of quota and be supplied to Business Stream detection via Gy interface.Using
Redirecting of installation of trying to be the first instructs or stops the request servicing, Diameter diameter credit control application DCCA client (such as gateway)
When business reaches, Business Stream can be taken with action and without waiting for the response from OCS.
